Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a session processing method, apparatus, device and storage medium. Background Technology

[0002] With the continuous development of communication technology, Multicast Broadcast Service (MBS) has been widely used because it can be performed when the User Equipment (UE) is in an idle or inactive state, which is a disconnected state.

[0003] In related technologies, after a UE receives the MBS service configuration information sent by a network device, it remains in a waiting-to-receive state until the network device begins sending service data. For a UE in this waiting-to-receive state, it only begins receiving MBS service data after receiving an activation instruction from the network device.

[0004] However, due to complex geographical locations and other reasons, it is easy for UEs to be unable to listen to the instruction information sent by network devices, and thus be unable to perform the corresponding MBS services. Summary of the Invention

[0089] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0090] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0091] To make it easier to understand, let's first combine Figure 1 The application scenarios of the embodiments of this application are described as follows:

[0092] Figure 1 This application provides an illustrated scenario diagram for the embodiments of this application. For example... Figure 1 As shown, the scenario includes: user equipment 101 and network equipment 102.

[0093] The user equipment 101 mentioned above can be either a wireless terminal or a wired terminal. A wireless terminal can be a device that provides voice and / or other service data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core network devices via a Radio Access Network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) or a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device, which exchanges voice and / or data with the RAN. For example, a wireless terminal can also be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or other similar devices. A wireless terminal can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, access terminal, user terminal, user agent, user device, or user equipment; no specific terminology is used here. Optionally, the aforementioned terminal devices can also be smartwatches, tablets, or other similar devices.

[0094] The aforementioned network device 102 can be a base station, specifically a base transceiver station (BTS) and / or base station controller in Global System for Mobile communication (GSM) or Code Division Multiple Access (CDMA), a base station (NodeB, NB) and / or Radio Network Controller (RNC) in Wideband Code Division Multiple Access (WCDMA), an evolved Node B (4G base station or eNodeB) in Long Term Evolution (LTE), a relay station or access point, or a base station (5G base station) in a future 5G network, etc. The embodiments of this application are not limited herein.

[0095] It should also be noted that the above... Figure 1 For illustrative purposes, the above scenario may also include other network devices or terminal devices, such as wireless repeater devices and wireless backhaul devices, etc. Figure 1 (not shown in the image), and each of the terminal devices and network devices in the above scenario is shown as an example, but is not limited thereto.

[0096] When performing MBS services, network device 102 first sends MBS service configuration information to user equipment 101, thereby realizing parameter configuration between network device 102 and user equipment 101.

[0097] After configuration, network device 102 may not immediately send the actual MBS service data. At this time, user equipment 101 is in a waiting state. Only after receiving the activation instruction or service start instruction sent by network device 102 will user equipment 101 start receiving MBS service data.

[0098] In practical applications, network device 102 typically uses paging messages to send activation instructions or service start instructions to user equipment 101. That is, if network device 102 starts sending service data for a certain MBS service, it carries activation instructions or service start instructions in the paging message to notify user equipment 101.

[0099] Accordingly, after configuration, user equipment 101 listens for paging messages at the paging occasion (PO) corresponding to user equipment 101, thereby obtaining activation indication or service start indication, and receiving service data of MBS service as needed.

[0100] However, in some scenarios, user equipment 101 may not be able to detect paging messages. For example, when the geographical location of user equipment 101 is complex, user equipment 101 can easily enter coverage gaps / holes. At this time, the UE cannot camp on any cell and cannot listen to any system information or paging information.

[0101] The inventors discovered that when user equipment 101 leaves a coverage vulnerability / hole, it searches for a signal to access a suitable cell for camping. However, user equipment 101 is unaware of the current session status of the MBS service, and even if it leaves the coverage vulnerability / hole, it cannot receive MBS service data normally.

[0102] To address the aforementioned issues, embodiments of this application provide a session processing method, apparatus, device, and storage medium. When user equipment 101 leaves an overlay vulnerability / hole, user equipment 101 proactively initiates a session status query for the MBS service to obtain the session status of the MBS service. Subsequently, based on the session status, corresponding operations are performed to obtain the service data of the MBS service.

[0103] It should be understood that the technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems may include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR). All of these systems include terminals and network equipment. The systems also include a core network component, such as Evolved Packet System (EPS) and 5G system (5GS).

[0104] The communication system to which the technical solution provided in this application applies includes network devices and UEs. The network devices may include access network devices and core network devices. For example, the access network devices may be wireless access network devices.

[0105] It should be understood that the methods and apparatus provided in the embodiments of this application are based on the same application concept. Since the methods and apparatus solve problems in similar principles, the implementation of the apparatus and methods can refer to each other, and repeated parts will not be described again.

[0106] The technical solutions of the embodiments of this application and how the technical solutions of this application solve the above-mentioned technical problems are described in detail below with specific examples. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0107] In practical applications, there are multiple ways for a UE to query the session status of an MBS service. This application embodiment does not impose specific limitations. For example, on the one hand, a user equipment can directly initiate a session status query for a specified MBS service to the network device to query the session status of the specified MBS service.

[0108] On the other hand, user equipment can also initiate MBS service queries to network equipment that are in a specified session state, in order to query MBS services that are in a specified session state.

[0109] Next, combined Figure 2 and Figure 3 The examples shown illustrate the two query methods described above:

[0110] Figure 2 Signaling interaction diagram of a session processing method provided in this application embodiment Figure 1 .like Figure 2 As shown, in the session processing method provided in this embodiment, the UE and the network device specifically perform the following steps:

[0111] S201, The UE sends a query request to the network device.

[0112] The query request carries the service identifier of the MBS service and is used to query the session status of the MBS service.

[0113] This application does not specifically limit the type of MBS service. For example, the MBS service can be a service that the UE is interested in.

[0114] It should be noted that the method of sending the query request is not limited in this application embodiment. For example, the query request can be sent through either dedicated signaling or public signaling.

[0115] In some embodiments, if the UE is currently in a connected state, it can send the query request to the network device via dedicated signaling.

[0116] In other embodiments, if the UE is currently in a disconnected state, such as an IDLE state or an INACTIVE state, the UE can send a query request to the network device via common signaling; or, the UE can be controlled to enter a connected state first, and then the query request can be sent to the network device via dedicated signaling.

[0117] In this embodiment of the application, by providing multiple ways to send query requests, it can be applied to UEs in different states, thereby meeting the needs of multiple scenarios and further improving the reliability of session state query.

[0118] S202. The network device sends a response message to the UE based on the query request.

[0119] Accordingly, after receiving a query request, the network device obtains the service identifier of the MBS service carried in the query request, determines the session state of the MBS service corresponding to the service identifier based on the service identifier, and sends a response message to the UE, which carries the session identifier of the session state of the MBS service.

[0120] It should be understood that the embodiments of this application do not limit the method by which the network device sends the response message. For example, the response message can be sent by at least one of dedicated signaling, paging message, broadcast message and multicast message.

[0121] S203. The UE receives the response message sent by the network device and performs service operations related to the session state according to the different session states of the MBS service.

[0122] In some embodiments, taking the query request containing the service identifier of the MBS service that the UE is interested in as an example, this step specifically involves receiving a response message sent by the network device carrying the session status of the MBS service that the UE is interested in.

[0123] It should be understood that the session state includes at least one of the following: start state, active state, not started state, inactive state, deactivated state, and stopped state. The UE can perform different service operations according to the current session state of the MBS service. The specific execution method will be shown in subsequent embodiments.

[0124] In some embodiments, the UE can query the session status of multiple MBS services simultaneously, that is, the query request carries the session identifiers of multiple MBS services.

[0125] Correspondingly, the response message sent by the network device can contain the session states of multiple MBS services. The UE can perform service operations related to the session state according to the different MBS service session states.

[0126] In this embodiment, a query request is sent to the network device to query the session status of the MBS service; a response message is received from the network device, carrying the session status of the MBS service; and service operations related to the session status are executed according to the different session statuses of the MBS service. This solution allows the UE to proactively initiate a session status query for the MBS service when it cannot detect indications sent by the network device. This avoids the problem of the UE being unable to start receiving the MBS service due to missing session status change indications sent by the network, or being unable to determine whether the service has ended, thus ensuring the normal operation of the MBS service.

[0127] In one possible implementation, in step S203 above, the UE receives a response message sent by the network device and performs service operations related to the session state according to different session states of the MBS service, specifically including the following situations:

[0128] (1) If the session state of the MBS service is in the start state or the active state, then the operation of obtaining the service data of the MBS service from the network device is triggered.

[0129] In some embodiments, it is also necessary to obtain the service data operation of the MBS service from the network device according to the current connection status of the UE and the type of MBS service.

[0130] For example, if the MBS service is a connected service, the UE needs to be in a connected state to obtain service data.

[0131] That is, if the UE is currently in connected mode, it can directly obtain the service data of the MBS service from the network device side; if the UE is currently in disconnected mode such as IDLE or INACTIVE mode, the UE needs to enter connected mode before obtaining the service data of the MBS service from the network device side.

[0132] Correspondingly, if the MBS service is a disconnected service, the UE can obtain the service data of the MBS service even when it is in a connected / disconnected state.

[0133] This solution allows the UE to receive service data based on its state, enabling the UE to enter a non-connected state such as IDLE or INACTIVE before the network device begins sending MBS service data. This avoids the power consumption caused by prolonged connection to the network, reducing UE power consumption without affecting the normal reception of service data.

[0134] (2) If the session status of the MBS service is any of the following states: not started, not activated, or deactivated, then the operation of continuing to monitor the session status of the MBS service will be triggered.

[0135] In some embodiments, when the session status of the MBS service is in an inactive, deactivated, or inactive state, it indicates that the network device is not currently sending service data for the MBS service, and the UE can continue to monitor the session status of the MBS service.

[0136] (3) If the session status of the MBS service is stopped, then the operation of leaving the MBS service will be triggered.

[0137] In practical applications, if the session status of the MBS service is stopped, it means that the network device has completed the transmission of the MBS service data. At this time, the UE can leave the MBS service to avoid the power consumption waste caused by continuous listening.

[0138] Next, combined Figure 3 The illustrated embodiment provides a detailed explanation of the scheme for querying MBS services in a specified session state:

[0139] Figure 3 Signaling interaction diagram of a session processing method provided in this application embodiment Figure 2 .like Figure 3 As shown, in the session processing method provided in this embodiment, the UE and the network device specifically perform the following steps:

[0140] S301, the UE sends a query request to the network device.

[0141] The query request is used to request the session identifier of the MBS service in the specified session state, and the query request carries the service identifier of the specified session state.

[0142] In some embodiments, the session state is specified as one or more of the following states: start state, active state, not started state, inactive state, deactivated state, and stopped state.

[0143] For example, if a UE wants to query the MBS service that is currently active, it can include the session identifier corresponding to the "active state" in the query request.

[0144] It should be noted that the method of sending the query request is not limited in this application embodiment. For example, the query request can be sent through either dedicated signaling or public signaling.

[0145] On the one hand, if the UE is currently in a connected state, it can send the query request to the network device through dedicated signaling.

[0146] On the other hand, if the UE is currently in a disconnected state, such as IDLE or INACTIVE, the UE can send a query request to the network device via common signaling; or, the UE can be controlled to enter a connected state first, and then the query request can be sent to the network device via dedicated signaling.

[0147] In this embodiment of the application, by providing multiple ways to send query requests, it can be applied to UEs in different states, thereby meeting the needs of multiple scenarios and further improving the reliability of session state query.

[0148] S302. The network device sends a response message to the UE based on the query request.

[0149] The response message contains the service identifier of the MBS service in the specified session state.

[0150] Accordingly, after receiving a query request, the network device obtains the session identifier carried in the query request, determines the MBS service in the specified state based on the session identifier, and sends a response message to the UE, which carries the service identifier of the MBS service.

[0151] It should be understood that the embodiments of this application do not limit the method by which the network device sends the response message. For example, the response message can be sent by at least one of dedicated signaling, paging message, broadcast message and multicast message.

[0152] S303. The UE receives a response message sent by the network device and performs service operations related to the MBS service according to the MBS service in the specified session state.

[0153] In this step, the UE can perform different service operations according to different MBS services. The specific execution method will be shown in subsequent embodiments.

[0154] In this embodiment, a query request is sent to the network device. The query request requests the session identifier of an MBS service that meets a specified session state, and the query request includes the specified session state. A response message is received from the network device, and the response message carries the session identifier that meets the specified session state. Based on the MBS service with the specified session state, service operations related to the MBS service are executed. This solution allows the UE to proactively initiate a session state query for the MBS service from the network device when the UE cannot detect the instruction information sent by the network device. This avoids the problem of the UE being unable to start receiving the MBS service due to missing the session state change instruction sent by the network, or being unable to determine whether the service has ended, thus ensuring the normal operation of the MBS service.

[0155] In some embodiments, a UE can simultaneously query MBS services corresponding to multiple specified session states. That is, the query request can carry session identifiers corresponding to multiple specified states. For example, if the UE wants to query MBS services that are currently in the active state and the start state, the query request can carry the session identifiers corresponding to the "active state and start state".

[0156] Correspondingly, the response message sent by the network device can contain multiple session identifiers for MBS services corresponding to various specified session states. The UE can perform service operations related to the MBS service according to different MBS services.

[0157] In one possible implementation, in step S303 above, the UE receives a response message sent by the network device and performs service operations related to the MBS service according to the MBS service with the specified session state. Specifically, this includes the following situations:

[0158] (1) If the specified session state is the start state or the active state, and the session identifier of the specified session state contains the session identifier corresponding to the MBS service that the UE is interested in, then the service data of the MBS service that the UE is interested in is triggered to be obtained from the network device.

[0159] For example, if the UE queries an MBS service that is in the start or active state, it determines whether the response message sent by the network device contains the session identifier of the MBS service of interest. If so, it obtains the service data of the MBS service of interest.

[0160] In practical applications, it is also necessary to obtain MBS service data operations from the network device based on the UE's current connection status and the type of MBS service. It should be understood that this solution is different from... Figure 2 The schemes and principles in the illustrated embodiments are similar, and can be referred to the above embodiments for details, which will not be repeated here.

[0161] (2) If the specified session state is the start state or the active state, and the session identifier of the specified session state does not contain the session identifier corresponding to the MBS service that the UE is interested in, then the operation of continuing to monitor the session state of the MBS service will be triggered.

[0162] (3) If the specified session state is any of the states of not started, not activated, or deactivated, and the session identifier of the specified session state contains the session identifier corresponding to the MBS service that the UE is interested in, then the operation of continuing to monitor the session state of the MBS service is triggered.

[0163] It should be noted that the specific method of monitoring the session state of MBS services as shown in the above embodiments is not limited in this application embodiment.

[0164] On the one hand, it can monitor the session status of MBS services at any PO location.

[0165] On the other hand, the UE can also monitor the session status of MBS services at the UE's associated PO location.

[0166] It should be understood that the embodiments of this application do not specifically limit the relevant PO location. For example, it can be the PO location closest to the UE.

[0167] For example, for a UE in an unconnected state such as IDLE or INACTIVE, it receives a Paging message from the network at a determined PO location associated with its UE identifier. If the UE determines that the loss of coverage and the restoration of coverage are still within the same modification period (e.g., Paging broadcasts an MBS session start indication for a modification period), or if the UE has missed its own PO location, then the UE can arbitrarily select the nearest PO to listen for indications of MBS session start / activation / not started / not activated / deactivation.

[0168] Specifically, for UEs in idle states such as IDLE and INACTIVE, or UEs in inactive states, both the network device and the UE calculate the PO position based on the same input. Different UEs listen to different POs in different times based on their different UE identifiers. The UE can listen to the paging messages sent by the network device in the PO to determine whether the network device has paged it, and listen for system information modification indications, or ETWS / CMAS indications, etc.

[0169] For UEs in connected mode, since they have entered the connected state, they do not need to listen for whether the network device has paged them. They only need to listen for system information modification indications or ETWS / CMAS indications. Therefore, UEs in connected mode can listen to any PO in each system information modification cycle to obtain the above indication information.

[0170] This solution increases the chances for the UE to listen to Paging messages, giving the UE more opportunities to view the session status of the service and further improving the probability of obtaining relevant information about the MBS service. It avoids situations where the UE cannot start receiving the MBS service or cannot determine whether the service has ended due to missing the session status change indication sent by the network device, thus ensuring the normal operation of the MBS service.

[0171] In some embodiments, before sending a query request to the network device, a blind check can be performed on the session status of the MBS service that the UE is interested in. If the session status of the MBS service that the UE is interested in is detected, then no query is required.

[0172] The following describes this solution with reference to specific embodiments:

[0173] Figure 4 Signaling interaction diagram of a session processing method provided in this application embodiment Figure 3 .like Figure 4 As shown, in the session processing method provided in this embodiment, the UE and the network device specifically perform the following steps:

[0174] S401. The UE performs a blind check on the session status of the MBS service that the UE is interested in.

[0175] Specifically, after the UE restores coverage, it enters the connected state and sends a query message to the network device. This query message is used to check whether the MBS service that the UE is interested in is in the specified session state.

[0176] For example, it is possible to query whether the MBS service that the UE is interested in is in at least one of the following states: start state, active state, not start state, inactive state, deactivated state, and stopped state.

[0177] S402. If the session status of the MBS service is found to meet the preset requirements, the service data of the MBS service that the UE is interested in is obtained from the network device.

[0178] In summary, taking the query to see if the MBS service that the UE is interested in is in the start state as an example, if the MBS service is detected to be in the start state, it is determined that the session state of the MBS service meets the preset requirements, and at this time, the service data of the MBS service that the UE is interested in is triggered to be obtained from the network device.

[0179] It should be noted that the method of obtaining MBS service data from network devices is as follows: Figure 2 and Figure 3 The embodiments shown have been described accordingly. For specific solutions, please refer to the above embodiments, which will not be repeated here.

[0180] S403. If the session status of the MBS service does not meet the preset requirements, a query request is sent to the network device.

[0181] Correspondingly, if it is detected that the MBS service is not in the started state, it is determined that the session state of the MBS service does not meet the preset requirements, and a query request is sent to the network device.

[0182] Optionally, the UE can also initiate multiple blind tests for the same MBS service. During the multiple blind tests, it can determine that the session state of the MBS service does not meet the preset requirements, including the following situations:

[0183] Within the preset blind detection time, the session status of MBS services detected multiple times in blind detections does not meet the preset requirements; and / or,

[0184] Within the preset number of blind detections, the session status of MBS services detected multiple times does not meet the preset requirements.

[0185] It should be noted that the preset blind detection time and preset number of blind detections can be set according to the parameters of the user's equipment, and this application embodiment does not impose specific limitations.

[0186] S404. Send a response message based on the query request.

[0187] S405. Receive the response message and, based on the MBS service in the specified session state, perform service operations related to the MBS service; or, based on the session state of the MBS service, perform service operations related to the session state.

[0188] It should be noted that the principles and beneficial effects of the solutions shown in steps S404 to S405 are the same as those in other solutions. Figure 2 and Figure 3 The solutions in the illustrated embodiments are similar, and you can refer to the corresponding solutions in the above embodiments for details, which will not be repeated here.

[0189] In this embodiment, by performing blind detection on MBS services, when the session state of the MBS service is detected to meet preset requirements, the service data of the MBS service can be directly acquired, thereby improving the efficiency of acquiring the session state of the MBS service and enabling the MBS service session to be initiated as soon as possible. When the session state of the MBS service is detected to not meet preset requirements, the UE can also... Figure 2 or Figure 3 The solution in the illustrated embodiment proactively initiates a session status query for the MBS service to the network device, which can improve the reliability of the solution and ensure the normal operation of the MBS service.

[0190] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some of the steps in the figures may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the sub-steps or stages of other steps.
